Three friends accidentally switch on a strange invention that starts turning their school laboratory into something far less ordinary.
It was one of those gloomy, rainy Thursdays when the school on Windmill Street looked permanently tired, as if even the walls wanted to go home. Emil, Lena and Patryk slipped along the corridor on tiptoe, carrying a stack of batteries, a torch, and the kind of guilty expressions that usually meant trouble was already halfway done.
They had been using the abandoned technical lab in the basement for two months now. It was officially off-limits, which only made it more appealing. Between the dust, the pastry boxes, and an ancient radio that still crackled like it had opinions, they had built their own hideout-laboratory. Missing pens, rulers, and other school supplies had also found a sort of new life there, scattered across desks in what Emil insisted was not a mess, but a system no one else understood yet.
That day, Lena arrived with something she had pulled from the attic at her grandfather’s house: a strange old device with too many buttons, too many knobs, and a faint smell that suggested it had once survived either a fire or a bad decision. She set it on the workbench with a grin.
“Come on,” she said. “Let’s see if it still works.”
Emil reached for the battery pack like a man preparing to launch a rocket. Patryk, who had been trying to look cautious and failing, sneezed into his sleeve at exactly the wrong moment.
Nothing happened.
Then nothing happened again.
Lena leaned closer and tapped the tiny screen. Emil pressed the green button. Patryk, determined to be helpful, pressed two buttons at once. The device gave a low hum, then burst into life with a flash of blue light so bright they all flinched back at the same time.
Letters crawled across the screen:
MODE: ADVENTURE ACTIVE
The lab went silent for half a second.
Then the wall nearest the door lit up with a huge hand-drawn map they had never seen before. Markers slid by themselves across the shelves. In the cupboards, something began to rattle, then roll, then clunk to the floor one after another: a turbo pen that shot out paper balls, a backpack with a tiny whirring vacuum hidden inside, and a helmet with a blinking antenna that glowed an embarrassed shade of blue.
Emil stared at the room. “I’m fairly sure this is either genius or a complaint waiting to happen.”
Lena was already putting on the helmet. It crackled immediately and spat out a stream of words that sounded suspiciously like badly translated Polish, or possibly very offended Klingon.
Patryk lifted the backpack vacuum, listened to it gurgle, and slowly lowered it again. “I don’t like how alive that sounds.”
Before anyone could answer, the lab door slammed shut with a bang that made the windows tremble.
A voice came through the speakers overhead, cheerful in the way only bad news can be.
“Task one: find the hidden ingredient. Time starts now.”
The lights began to flash red, then green, then red again. The floor gave a small, nervous shake.
Emil, Lena and Patryk froze, staring at one another, because none of them had turned anything on, and none of them had any idea what the hidden ingredient was supposed to be.
Then, from somewhere beneath the wardrobe, came a sharp crunch.
Something inside the shadows moved. And whatever it was, it was starting to push its way out.
